Why is bitcoin going 3% up each day?
Here is reasons that I can think of:
[1] Anticipation of Segwit2x in November 16.
[2] CME news
[3] Amazon rumor that they are going to accept bitcoin as mode of payment.
So this fresh of positive news really bring investors to get bitcoin and invest on it because the price can go to the moon later. And the more positive news, the more bitcoin price picks up. But just remember that we can't always go up, sometimes a healthy correction is needed. Just enjoy this massive bull run before it hits the break.
Positive news like this can really make a difference in the price trend. A lot believe that it will go up and a lot would buy thus increasing the demand for correction. It's possible that it will continue to go up for some time now since these positive news just popped up, then there may be some price corrections after. With regards to the upcoming segwit2x in November, everyone must be trying to buy some bitcoin right before that happens.
